Why Scars Stay Red, Dark or Pigmented (And What Helps)

The Cut Closed Up. The Colour Did Not.

You ran your finger across it again this morning. The cut closed up months ago, but the colour has not. Some days it looks pink, some days angry red, some days a stubborn brown that catches your eye every time you look in the mirror. People still ask what happened, and you are tired of explaining.

You are not imagining it. Scar colour can take far longer to settle than the wound itself, and on some skin it stays longer than expected. The good news is that there is usually a reason, and usually something you can do.

Why Some Scars Stay Coloured

When skin is broken, the area below produces new collagen, blood vessels, and sometimes extra pigment as it recovers. Most of this settles within 12 months, and the scar quietly fades to a pale line. But not always.

If the recovery process continues to produce pigment longer than usual, you end up with a brown or grey scar (post-inflammatory hyperpigmentation). If the new blood vessels do not retreat as expected, you end up with a red, pink, or purple scar (vascular). Both are common, both are normal, and both respond to gentle care in different ways.

The Two Main Types of Coloured Scar

Red, pink, or purple scars (vascular). These look angry, sometimes slightly raised, and can flush after exercise, alcohol, or heat. The colour comes from extra small blood vessels that have not retreated. Most fade across 6 to 18 months. Some take longer, especially on the face and chest.

Brown, grey, or dark scars (pigmented). These are flatter than red scars but darker than surrounding skin. The colour comes from extra melanin produced during recovery. More common on darker skin tones and on any skin exposed to the sun while the scar was new. They fade over months to years.

Both at once. Some scars start red and finish brown, especially in summer.

How Long Scar Colour Normally Takes to Fade

Most scars look their reddest or darkest at 6 to 12 weeks, then slowly improve. By 12 months, redness has usually faded significantly. Brown pigmentation often takes longer, sometimes 18 to 24 months, and is the most affected by sun exposure during that window.

If your scar is still coloured at 12 months, it is not necessarily permanent. It often just needs more time and consistent care.

What Actually Helps Fade Scar Pigmentation

Daily SPF 50 over the scar. The most important step by a long way. Sun exposure on a coloured scar locks in pigment and slows fading by months. In Australia, this matters even more.

A silicone-based scar gel twice daily. Silicone supports scar appearance and may help even colour over time. Works on both red and pigmented scars, though red usually fades slightly faster.

Hydration. A well-moisturised scar reflects light more evenly and looks less stark against surrounding skin.

Time and consistency. Scar colour fades slowly. Three months of daily care often shows the first real shift.

Brightening ingredients on surrounding skin (not on a fresh scar). Niacinamide and gentle vitamin C derivatives applied around a recent scar can support a more even surrounding tone.

Where Genova Scar Gel Fits

Genova Scar Gel is an Australian-made silicone-based gel formulated for the appearance of scars, including discoloured ones. Applied as a thin layer twice daily for at least 12 weeks, it can support both red and pigmented scars alongside daily SPF. For pigmentation extending beyond the scar onto surrounding skin, a brightening serum can be used around the area once recovery is well established. Genova is manufactured in Australia in accordance with TGA-compliant standards.

SPF for Coloured Scars in Australia

This is the most important step, and the one most people skip. UV on a coloured scar darkens it permanently and stalls everything else you are doing. Even brief exposure on a fresh scar (a walk to the letterbox, a drive to work) adds pigment over time.

SPF 50, broad-spectrum, daily, reapplied if outdoors. For chest and hand scars, this often means SPF on areas you do not normally protect.

What Does Not Help (And Often Makes It Worse)

Strong acids or scrubs on the scar. AHAs, BHAs, and physical scrubs can deepen pigmentation rather than fade it.

Lemon juice or DIY brightening tricks. These cause irritation that often results in more pigment.

Sun exposure "to even out the tan." Tanning a scar darkens it more than the surrounding skin, making it more obvious.

Picking, scratching, or rubbing. Anything that irritates a coloured scar extends the pigmentation phase.

Strong actives applied directly to a recent scar. Retinol and high-strength vitamin C applied to fresh scars can cause increased colour.

Realistic Expectations for Coloured Scar Recovery

With daily silicone and daily SPF, most red scars fade within 6 to 12 months. Pigmented scars usually take longer, often 12 to 24 months, and may not fade completely. The scar shape stays. The colour can quieten significantly.

For coloured scars that remain distressing after 12 months of consistent care, in-office options like vascular laser (for red scars) or pigment-targeted laser (for brown scars) may help. A qualified skin professional is the best person to advise.

Who This Approach Suits and Who It Does Not

It may suit you if:

• Your scar is closed, but the colour has not settled
• You are willing to apply SPF over the scar every day
• You can commit to a silicone gel twice daily for at least 12 weeks
• You want a gentle, low-cost first step before considering laser

It may not suit you if:

• Your scar is still recovering and not yet fully closed
• You expect the colour to disappear within weeks
• You have a keloid or significantly raised scar (different plan needed)
• You are not willing to wear SPF over the area daily

Pros and Cons of a Daily Routine for Coloured Scars

Pros: evidence-supported, gentle, low cost, works on both red and pigmented scars, no downtime, supports both fading and texture.

Cons: takes months to see change, requires daily SPF, results are partial, will not match in-office laser for stubborn cases.

Frequently Asked Questions About Coloured Scars

Why is my scar still red after a year?
Some scars take 12 to 18 months for redness to fully settle, especially on the face and chest. Daily SPF and silicone support continued fading.

Why has my scar gone darker, not lighter?
Usually sun exposure during recovery, or post-inflammatory hyperpigmentation. SPF and silicone-based care can help even the tone over time.

Can a brown scar fade completely?
Often yes, but it can take 18 to 24 months of consistent care. Some pigmented scars fade significantly but not entirely.

Will makeup cover a coloured scar?
Yes, in the short term. Concealers work daily, but SPF and silicone are what change the underlying colour.

Is laser better than scar gel for red scars?
For stubborn red scars after 12 months of topical care, a vascular laser may give faster results. Topical care still matters alongside laser.

Can I use scar gel on a scar that is already faded?
Yes. It continues to support appearance and texture even on partially faded scars.

A coloured scar is not stuck. It is just on a slower timeline than the wound itself was. With daily SPF, a silicone-based gel twice a day, and a few quiet months of consistency, most scars fade from angry to almost unnoticed. The cut closed up. With time, the colour can too.
